Title: Feed mechanism for stacked items
Inventor: BLOEMENDAAL STANLEY DALE
IPC: B65H5/06
Filed: 1969-02-07
Abstract: 1,245,024. Feeding sheets; delivering sheets. GENERAL DESIGN Inc. 7 Feb., 1969 [7 Feb., 1968], No. 6889/69. Heading B8R. Sheet-feeding apparatus comprises a holder for a stack of sheets, suction means for bending the part of the end sheet away from the stack and means for withdrawing the bent sheet from the holder, the suction means including an element having a contact surface, part of which is in the plane of the end sheet at the pick-up position, and part of which is inclined outwardly in the direction of a corner of the sheet. General arrangement, Fig. 2.-Data cards stacked in hopper 60 are separated by mechanism 20 from the bottom of stack 76 and are fed between guides 27, 29 to nip collars 24, 26 and thence past a read head 21 to a further pair of rollers 24, 26. The cards then pass through guides 34, 42 to roller pair 31, 33, and are stacked in hopper 36. A gate 44 is opened in response to a signal from the card reader to allow a card to pass through, and closes automatically after a time interval; if the gate cannot close, due to a jammed card, the card reader is stopped. Stacking sheets, Fig. 2.-The hopper 36 is formed with a bottom wall 37 having openings 48 which accommodate rollers 38 carried on pivoted arms 56. As each card passes through the entry throat of the hopper, the rollers 38 bounce the stack away from wall 37 to allow the card to pass into a space between the wall and the bottom of the stack. A follower 51 on a pivoted arm 53 engages the top of the stack. Separating sheets.-The hopper 60 and follower 71 are constructed in the same fashion as the receiver, above; the bottom wall 78, Fig. 6, does not extend completely along the bottom of the stack, an opening 81 being provided at the end nearest side wall 64. A suction element 95 (also Figs. 8, 9, not shown) is pivotable into and out of contact with the lowest card 170 in the stack under the action of solenoid 91 and a connecting link mechanism 109, 121, 120, 112, 125, 127. The application of suction is also controlled by a synchronously acting valve mechanism (Figs. 10, 11, not shown). The suction element 95 can pivot to a position above the horizontal, which is adjustable between screw 181 and plate 180. The bottom card 170 is bent away from succeeding card 175 and the bent end 173 is introduced between continuously driven roller 155 and idler roller 167 carried by link 124 into co-operating position (Fig. 7, not shown).

Title: Process for the production of novel lighting effects
IPC: F21V9/00
Filed: 1961-02-27
Abstract: 978,417. Lighting effects; filters. E.M. SANDOZ. Feb. 27, 1961 [Feb. 26, 1960], No. 7150/61. Heading G2J. Novel lighting effects are obtained using coloured lights obtained by filtering light from incandescent filament lamps through red and blue filters having specific transmission characteristics. The red filter has a transmittance in the region from 380 to 580 mÁ which does not exceed 0. 5% and a transmittance curve which rises very rapidly in the long-wave region of the visible spectrum from a value close to zero to a value which is close to its maximum transmittance in this region and which has a point of inflection in the spectral region from 600 to 640 mÁ. The blue filter has a transmittance in the visible spectral region below 425 mÁ and above 560 map which does not exceed 0. 5% and a transmittance curve which has a maximum in the region of 460-480 mÁ and whose width at half of its maximum value is smaller than 75 mÁ. The lights may be used successively or in combination. The filters may be made of glass, gelatine, cellulose ester of synthetic resin. The invention may be applied for example to stage lighting effects in theatres, identification of dyes and pigments for the detection of counterfeits and in the medical examination of blood samples &c.

Patent GB-609521-A (GB)
Title: A new or improved method of joining metal sheet or strip
IPC: F16B5/00
Filed: 1946-03-08
Abstract: 609,521. Sheet-metal Joints. CHISHOLM, J. March 8, 1946, No. 7293. [Class 83 (iv)] Two sheets or strips 1, 2, 3, 4 are joined end to end to form one length by transversely slitting at 11, 13 one or more edges of each end, displacing the metal at one side of each slit, e.g. bending at 19, 20 through 90 degrees, placing the two ends in overlapping relationship with the strips in alignment, Fig. 3, and bending the displaced portions 18, 21 each around a slit edge of the other strip and away from the adjacent end edge of its own strip, Fig. 4. Portions 16, Fig. 1, may be cut away. More than two lengths may be joined thus and, if they are to be passed through a pickling bath, the final bends may be effected by means of a wedge-shaped plate 25, Fig. 3, which bends down the ears 18, and feeding rollers 24, which bend down the flaps 21, which have been bent to position 21a in the bath. If the strip is cleaned by passing between rotary brushes, these may be spring-mounted and fitted with metal end-discs which, when they engage the joint, separate the brushes and prevent damage. Rubber squeezee rollers to remove the pickle solution may be arranged similarly. The method may be used to join two sheets by forming strip-like lugs thereon and joining the lugs of one sheet to the lugs of the other, or two spaced strips may be joined to one wider strip. If the metal is difficult to bend, the strips may be connected by an intermediate strip of easily bendable metal. The Provisional Specification describes a method of joining strips by forming openings in the edges of one strip so that the sides of each opening meet at an apex away from said edges and bending the end of the other strip around one of the sides of each of said openings so that it extends up to said apices.

Abstract: 432,058. Mantelpieces. ROBERTS, E. F. C., and BUILDERS MERCHANTS (LONDON), Ltd., Anchor Wharf, Windmill Lane, Thames Ditton, Surrey. March 7, 1934, Nos. 7328 and 21069. [Class 52 (iv)] [See also Groups XI and X] In a gas or electric fire comprising a slab of cement or the like having a facing of tiling or the like and an aperture 16 entirely surrounded by the slab and adapted to receive a fire unit, the facing material is provided with an angle edging 15 in the form of an angle sectioned frame around the slab, one flange overlying the face and the other projecting rearwardly over the side edges of the slab and securing means projecting inwardly from the angle edging into the slab. The facing may be of tiling, opalescent glass, decorated asbestos board, synthetic resin facings, marble and the like. In one form, Fig. 2 the securing means comprises screws 17 passing through the side flange of the edging and through angle shaped lugs 20 into wooden plugs 19 moulded in the slab 12. The lugs 20 are embedded in the wall 11 to which the fire is to be attached. In a modified form a screw passes through the front flange of the angle and through a tube cast into the slab and enters a plug in the wall. Alternatively the slab may be moulded on to the back of the facing the edging having members projecting into the slab and locked by means of binding wires to the slab reinforcement. Where the facing comprises glass having decorative material behind it, it is secured to the slab by a mastic adhesive. In a further method of fixing, wood blocks project from the wall into recesses in the slab and receive screws passing through the side flanges of the edging. The edges of the fire aperture are covered by a flange on the fire unit 35 which in the case of a comparatively thin slab may be brought forward by forming the flange 36 with a re-curved edge 37, Fig. 6. Fig. 8 shows a slab of irregular contour and having the facing in two main sections, 42, 43 of different materials. The joints between the sections are covered by a flat strip 44 integral with the angle edging 41 and provided with fixing wires extending into the slab between the facing sections. Specifications 23463/99 and 284,517, [both in Class 126], are referred to.
